In some embodiments, as shown in FIGS. 1-7 , the second terminal block 2is a pogo pin assembly or a contact set corresponding to a pin head ofthe pogo pin assembly. To achieve rapid assembling of the tabletopassembly and the lifting frame assembly, a connection mode of the firstterminal block 1 and the second terminal block 2 is configured to be theconnection of the pogo pin assembly and the corresponding contact set inthis embodiment. When the second terminal block 2 is one of the pogo pinassembly or the contact set, the first terminal block 1 needs to be setas another.

Further, the tabletop support 52 is provided with a positioning face 53,the positioning face 53 is located in at least part of the region of thetop of the supporting parts 51, and the positioning face 53 is in fitwith the bottom face of the tabletop. In this embodiment, the secondterminal block 2 is the pogo pin assembly, when the supporting parts 51move to an installation position, a direction of the pin head of thepogo pin assembly is perpendicular to the positioning face 53, and thepin head of the pogo pin assembly is higher than the positioning face53. In this embodiment, when the lifting frame assembly is assembledwith the tabletop assembly, the pin head of the pogo pin moves downwardsunder the pressure of the contact set located at the tabletop,therefore, after the bottom face of the tabletop 6 is in contact withthe positioning face 53, the pin head is kept at a state abuttingagainst the contact under the action of elastic force, thus achievingelectric connection of the tabletop assembly and the lifting frameassembly.

In some embodiments, as shown in FIGS. 1-7 , the number of at least twosupporting parts 51 is two, corresponding wiring modes of the pluralityof second electric connection contacts 21 respectively located at thetwo supporting parts 51 are configured to be circumferentially andsymmetrically arranged, and the circumference is perpendicular to heightdirections of the supporting parts 51 and takes the two supporting parts51 as end points of a diameter. In this embodiment, the plane where thecircumference is located is parallel to the bottom face of the tabletop6, and the second electric connection contacts 21 of another supportingpart 51 may be formed by rotating the corresponding wiring mode of thesecond electric connection contacts 21 located at one supporting part 51by 180 degrees along the circumference.

Specifically, the second electric connection contacts 21 in symmetricarrangement are shown in FIG. 7 , and a region IV in the figure is theposition of the center of circle of the circumference of thisembodiment. Ten second electric connection contacts 21 are provided oneach of the two supporting parts, and are distributed in a rectangulararray of 2×5. The driving unit 4 comprises two drivers 41, and thedriver 41 may be a motor.

The two supporting parts 51 are configured to be clamped in middlepositions of the two cross beams 521, are hinged to the cross beams 521through the hinge points 54, and are fixedly connected to the crossbeams 521 through the fixed connection points 55. In this embodiment,the supporting parts 51 may be hinged to the cross beams through thehinge points 54 before delivery so as to guarantee that the supportingparts 51 are in a rotatable state. After receiving the goods, the userrotates the supporting parts 51 to make the supporting parts 51 befixedly connected to the cross beams through the fixed connection points55.

It should be understood that the two hinge points in this embodiment arelocated at the inner sides of the two fixed connection points.Therefore, when each of the supporting parts 51 is rotated towards theinner side, the second terminal block 2 may sweep a roughly fan-shapedregion, so that the second terminal block 2 is hidden in a region formedby the cross beam 521 and the supporting part 51 (the position shown bya dotted line in FIG. 6 ) during packaging and delivery, and at themoment, the second terminal block 2 faces the two sides of the liftingframe assembly, thus playing a role in protecting the second terminalblock 2.

Further, the tabletop support 52 further comprises two girders 522, themiddles of the two girders 522 are fixedly connected to two ends of thecross beams 521, respectively; each of the girders 522 is provided witha connection point 56, and the supporting parts 51 are fixedly connectedto the girders 522 through the connection points 56. When the supportingparts 51 are fixed to the tabletop support 52, in this embodiment, thegirders 522 are further provided with the connection points 56 toachieve a better fixation effect during the fixation of the supportingparts 51 and the tabletop support 52. The connection point 56 on each ofthe girders 522 is located at one side, away from the hinge point 54, ofthe fixed connection point 55, thus forming three-point positioning bythe connection point 56, the fixed connection point 55 and the hingepoint 54 in a horizontal direction in the installation state to form thefixation of the lifting frame assembly to the utmost extent.

Optionally, in above embodiments, the hinge points 54 and the fixedconnection points 55 located on each of cross beams 521 may besimultaneously configured as racetrack-shaped positioning holesextending in a length direction of the cross beam 521 (as shown in anenlarged view in FIG. 5 ), so that the driving box 512 may also have adegree of freedom to move in the horizontal direction when the drivingbox 512 is connected to the cross beam 521. When the tabletop assemblyand the lifting frame assembly are in an assembling stage, the secondterminal block 2 located at the position of the driving box 512 may befine-adjusted in the horizontal direction through the racetrack-shapedpositioning holes, thus achieving a more accurate butt joint with thefirst terminal block 1.

Meanwhile, the connection point 56 of the above embodiment may also bearranged a recessed region (as shown in FIG. 3 ) formed by the bottom ofthe girder 522 recessed upwards, when the connection point 56 is used toconnect the girder 522 to the driving box 512 using a screw, the screwand the driving box 512 may be pre-assembled before delivery. The screwmay slide into the recessed region with the rotation of the supportingpart 51 when assembled by the user.
